I don't think you can read that into this case. One would expect these Justices to take a very broad view of 4th amendment protections. Criminal law is the one place liberal justices are hostile to big, activist government. But don't get me wrong, I don't this this was that broad a reading of the 4th amendment and was pretty much an easy slam dunk decision on the result. Scalia has always been pretty good on the 4th amendment and it doesn't surprise me at all sided with the liberals on the Court here.
They also stood up for a church school to fire someone that wasn’t acting according to their beliefs.
Recently, I have been very surprised with this court.
